# Difference between revisions of "Total Skill Index"

The Total Skill Index (or TSI) is an official measure of a player's abilities. The formula used for the calculation is unknown, but several somewhat successful attempts have been made in approximating the true function. It is rumoured that HT-Bjorn proclaimed he'll change the TSI calculation formula as soon as someone figures it out.[1]

Obviously, the higher TSI, the better. But it isn't very accurate because an average all around player (inadequate in a few positions) would have a higher TSI than specialized players (excellent in only one). It increases with training and it can increase and decrease with form. Sometimes your TSI will drop even though your form does not. (That is a background form change for example when you go from a high passable to a low passable form level. It doesn't show up as a form change but you dropped a sublevel)

TSI for goalies is a different matter. The highest TSI for a goalie the better. Since a goalie only specializes in one skill it can be measured and you can see how close your goalie is to the next level by entering your TSI into http://www.hottrick.org/hattrick_keeper_tool.php. Also keepers have higher TSI than their specialized equavalents.

A common theory is that both form and stamina have a multiplying effect on the TSI, whereas the other skills (for keepers, goaltending only) contribute as a sum of exponential functions.

The Set Pieces skill doesn't affect the TSI.

### What is the Question to the Answer of the Meaning of TSI?

^  Just_Y note: Really, REALLY sorry to barge in with non-HT related stuff, but I am obliged to quote "The Hitchhiker's Guide To The Galaxy" by Douglas Adams, stating before the begining of "The Resturant at the End of the Universe" at one side of the page -

"There is a thoery which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizzare and inexplicable."

Then you flip the page.

"There is another thoery which states

``` that this has already happened."
```

You ought to agree that the Estimated Player Price was much more explicable than the TSI.. The base of TSI must be 42.
